Abstract
The present invention provides a kind of powder metallurgy process, and by weight containing lubricant 1.6%, magnesium 1.3%, potassium 0.2%, ethene 3.1 3.2%, additive 3.2 4.1%, remaining is copper and is difficult to the impurity removed, and above-mentioned raw material are carried out into extruding crushing；Above-mentioned powder ingredients, by being stirred under 210~230 DEG C of high temperature, carry out die casting, reusable heat water is cleaned, antirust treatment, screening and drying afterwards with cooling liquid mix lubricant.Present invention manufacture can substantially reduce production cost, and intensity hardness is high.
Description
Technical field
The present invention relates to a kind of powder metallurgy process.
Background technology
Powder metallurgy is to produce metal dust or made with metal dust (or mixture of metal dust and non-metal powder)
For raw material, by shaping and sintering, the technology of manufacture metal material, composite and all kinds product.Powder smelting
Jin Fayu production ceramics have similar place, belong to sintered powder technique, therefore, a series of New Technologies In Powder Metallu Rgies also can use
In the preparation of ceramic material.The advantages of due to PM technique, it turns into the key for solving the problems, such as new material, in new material
Development in play very important effect.Powder metallurgy includes powder processed and product.Powder wherein processed is mainly metallurgical process, and word
Face coincide.And sintered metal product is then often far beyond material and metallurgical category, often across it is multidisciplinary (material and metallurgy,
Machinery and mechanics etc.) technology.Especially contemporary metal powder 3D printing [1-2], collection mechanical engineering, CAD, reverse Engineering Technology,
Layered Manufacturing Technology, Numeric Control Technology, material science, laser technology are so that sintered metal product technology turns into across more
The modern complex art of subject.Existing powdered metallurgical material manufacturing cost is high.
The content of the invention
(1) technical problems to be solved
The problem to be solved in the present invention is to provide a kind of powder metallurgy process, with overcome in the prior art manufacturing cost it is high
Defect.
(2) technical scheme
To solve the technical problem, the present invention provides a kind of powder metallurgy process, contains lubricant by weight
1.6%th, magnesium 1.3%, potassium 0.2%, ethene 3.1-3.2%, additive 3.2-4.1%, remaining is copper and is difficult to the impurity removed,
Above-mentioned raw material are subjected to extruding crushing；Above-mentioned powder ingredients pass through in 210~230 DEG C of high temperature with cooling liquid mix lubricant
Under be stirred, carry out die casting afterwards, reusable heat water is cleaned, antirust treatment, screening and drying.
Further, the additive weight ratio is 4%.
Further, the weight ethylene ratio is 3%.
(3) beneficial effect
The powder metallurgy process of the present invention, manufacture can substantially reduce production cost, and intensity hardness is high.
Embodiment
With reference to embodiment, the embodiment of the present invention is described in further detail.Following examples are used for
Illustrate the present invention, but be not limited to the scope of the present invention.
A kind of powder metallurgy process of the present invention, by weight containing lubricant 1.6%, magnesium 1.3%, potassium 0.2%, ethene
3.1-3.2%, additive 3.2-4.1%, remaining is copper and is difficult to the impurity removed, and above-mentioned raw material are carried out into extruding crushing；
Above-mentioned powder ingredients and cooling liquid mix lubricant carry out die casting by being stirred under 210~230 DEG C of high temperature afterwards,
Reusable heat water is cleaned, antirust treatment, screening and drying.
The additive weight ratio is 4%.The weight ethylene ratio is 3%.
The powder metallurgy process of the present invention, manufacture can substantially reduce production cost, and intensity hardness is high.
In summary, the restricted embodiment that it is the present invention that above-mentioned embodiment, which is not, all those skilled in the art
The modification carried out on the basis of the substantive content of the present invention or equivalent deformation, the technology category in the present invention.
